Transient thermal constriction resistance in a finite heat flux tube
- North Carolina State Univ., Raleigh, NC (United States)
The transient constriction resistance has been studied under idealized conditions in a semi-infinite medium with isothermal contact and in a semi-infinite cylinder with uniform heat flux over the contact. Although the transient constriction resistance in finite length cylinders has several practical applications, such a problem has not been analyzed, mainly due to mathematical difficulties involved in the solution for the case of isothermal contact. In this work we use a finite difference scheme with numerical grid generation technique to study the transient constriction resistance in a cylindrical heat flux tube of finite length with a circular contact surface. Two boundary conditions considered for the contact surface included the cases of uniform temperature and uniform heat flux. 10 refs., 3 figs.
